DA280 is a handheld ADSL2+ tester, which provides full testing and analysis of ADSL/ADSL2/ADSL2+Lines accurately and fast, covering physical layer, network layer and cable physical characteristics. Giving A visual determination of the quality of ADSL lines, it is a necessary and ideal tool for installation and Maintenance of the ADSL.
ADSL physical layer testing - Support all ADSL standards, including ANSI T1.413 Issue 2, ITU-T G. 992.1 G. Dmt, G. 992.2 G. Lite, G. 992.3 ADSL2, RE-ADSL2 and G. 992.5 ADSL2+ - Fast and interleave signal channel BER testing - Test upstream, downstream, maximum speed and channel utilization - Test upstream and downstream noise margin, output power, and power attenuation - Bit error statistics of NEC, FEC, CRC, and HEC - Automatically detect and display LOS, LOF, LOP, LOC and LOM with the comparison between history and present data - Error seconds statistics - Display every sub-channel of Bits per Tone by the mean of graphic and number
ADSL network layer testing - Support several upper layer protocols, including RFC2684, RFC1483, RFC2516 PPPoE, RFC2364 PPPoA, DHCP and PAP/CHAP etc. - PPPoE/PPPoA/DHCP to acquire IP address and Ping testing - Fixed IP Mode Ping testing - Ping testing that includes Ping loss testing with times and package size, Ping loopback latency testing with MAX, MIN and average - ADSL2+ modem replacement
Ethernet testing - LAN Ping testing
Cable testing - Digital Multi Meter, DMM is used to test loop resistance, insulation resistance, capacitance,AC/DC voltage and line length estimation - Tone generation
Others - Auto power-off - Sound and LED alarm indication - Data management - Software online upgrade
-Line quality pass/fail indicator: Users can set their own threshold parameters of the line,By comparing the actual test results with the threshold to determine the line quality pass or fail
-Tone generation: Send signal at one end, and then identify the tested line with tone generator at the other end
